Public bug reported: When I'm using my laptop, I sometimes see some noises on screen. they're mostly horizontal noise lines in panels (but sometimes on other parts). I attached a picture of the problem. I use Kubuntu 20.10. The problem is present when I connect my laptop to external screen (so it's not monitor's problem).
